IMPROVEMENT IN WASHING-MACHINES.

Specification forming part of Letters Patent No. 140,435, dated July 1,1873; application filed May 26, 1873.

To all whom it may concern:

Be it known that 1, WILLIAM M. ROWLAND, of Tyler, in the State of Texas,have invented "a new and useful Improvement in Washing- Machines, ofwhich the following is a clear, full, and exact description, referencebeing had to the accompanying drawings making a part of thisspecification, in which Figure l is a longitudinal vertical section, andFig. 2 is an end view of the machine.

My invention has reference to that class of washing-machines known asself-regulating machines; and consists in the arrangement forcontrolling at will the amount of pressure to be used, in combinationwith the construction of the feed and washing rollers.

To enable others skilled in the art to make and use my invention, I willproceed to describe the exact manner in which I have carried it out.

The water-boXA is made of any desirable height and length. Thewash-board B, at its lower end, rests upon the bottom of wash-box, andis secured by pins working snugly in the slots b, Fig. 1. The upperportion of the washboard curves to about one-quarter of a circle on itsface, (see Fig. 1,) and is suspended by the cords cl (1, which pass overthe pulley-roller D, (see Fig. 2,) and which are secured ate e to therack E, which holds the weight-box F, as shown in Fig. 1. The body ofthe washboard B consists of a series ofrevolvin g rollers, which Iusually construct octagonal that the angles may have a pressing-surfacewhen coming in contact with the clothes to be washed.

These rollers have proper hearings in each side of the frame of thewash-board B, and revolve closely together, as shown in Fig. 1, duringthe process ofwashin g. The cylindrical fluted roller 0 is placed acrossthe wash-box, having proper bearings on each side and above thewash-board B, so that the corrugations on the roller will mesh into theoctagonal rollers of the wash-board at its curved surface, as shown inFig. 1. The roller 0 is turned by means of the crank G. and has novertical play. The wash-board B is brought up against the roller 0 bymeans of cords d and the weight which may be placed in the weight-box F,which, bearing on the outer ends of the cords, causes them to raise thewash-board up to the roller 0.

It is evident that the pressure of the washboard upon the roller dependsupon the amount of weight placed in the box F attached to the rack E,the rear end of which is secured by the rodf, as shown in Fig. 1.

It is evident that as the clothes to be washed are fed between thewash-board andthe fluted roller 0 the machine will be self-regulatin gand self-adjusting to the work to be performed.

On the water-box, and over the large fluted cylinder 0, is frame ahaving the rollers c c, and secured to the frame of the box by hinges orany other suitable means. The pulley-roller D may have its bearin gs .inthis frame, as shown in Fig. 2. Over the rollers c c the clothes to bewashed may be regularly fed, and thus avoid choking the machine andsecure good work in the washing.

By means of the fluted cylinder and the octagonal rollers the finestclothes may be washed without injury, the desired pressure being securedin the manner already described. The machine is equally good for rinsingand washing clothes.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

In a self-regulating washing-machine, the fluted cylinder 0, incombination with the curved-face wash-board B, constructed with theoctagonal rollers b b, the cords d d, the pulley-roller D, the rack E,and weight-box F, all constructed and arranged as and for the purposedescribed.
